Halo Structure of 6He Analyzed via Ab Initio Correlations
Analysis
Key Takeaways
- •The paper uses ab initio calculations to study the structure of 6He.
- •Two-nucleon spatial correlations are key to understanding the halo structure.
- •Valence neutrons in 6He primarily form a spin-singlet configuration.
- •The halo neutrons are significantly further from the core than core nucleons are from each other.
- •Off-centering of the core is a major factor in the increased proton radius of 6He compared to 4He.
“The study demonstrates that two-nucleon spatial correlations, specifically the pair-number operator and the square-separation operator, encode important details of the halo structure of 6He.”
